One valve accounts for the amount of hot water that enters the radiator. The other valve, referred to as the lockshield valve, balances the system by regulating how much heat the radiator gives off.

Should both valves be open on a radiator?

You should open both of the valves on all of your system's radiator when you are starting the radiator balancing process. You will most likely need to use pliers to open the lockshield valve.

What are the two controls on a radiator?

Each radiator in your home needs a pair of radiator valves. One of the valves controls the amount of hot water entering the radiator and the other (known as the lockshield valve) balances the system by controlling how much heat the radiator emits.

Do you open both valves on a towel radiator?

Open both fully anticlockwise. Should heat up then ,providing central heating is on.

What are the two valves on a towel rail?

Your towel radiator has two valves to enable it to control the flow of hot water and the amount of heat it emits. One valve regulates the amount of hot water entering the towel radiator while the other controls the rate at which the hot water exits the radiator.

Multilux V two-point connection for radiators with integrated valves and bathroom radiators

How do I adjust the temperature on my bathroom radiator?

The most common method for adjusting temperature will be to adjust the knob by turning clockwise to turn off - I.e. cool or anti clockwise to open and up the heat. Turning the knob could be difficult, and so pliers might be required.

Should lockshield valve be open or closed?

As you progress further away from the boiler, the Lockshield valve will need to open slightly more. It's not uncommon for the Lockshield Valve in the first radiator to be open around one-quarter of a turn, while on the last radiator, it may need to be fully open.

How do bathroom radiator valves work?

The valves in a towel radiator control the flow of water through the pipes, ensuring your radiator heats up effectively and efficiently. They keep your towel radiator functioning and ensure that your bathroom is heated up when needed, and your towels are dry and ready to use.

What side of the radiator is the lockshield valve?

The lockshield valve, on the side of the radiator opposite the on/off valve, may be adjusted to balance the output of your heating system. The lockshield itself is the plastic cap that covers the valve to ensure that you don't accidentally change the setting once you've adjusted it.

Which is the lockshield valve on a towel radiator?

A lockshield valve is the valve on a radiator that has a plastic cap covering but not connected to the adjusting spindle. If you turn the cap it doesn't adjust the valve. To adjust the valve you have to remove the cap and turn the spindle with pliers.

What are the different valves on a radiator?

The different types of radiator valve are:

• Thermostatic Radiator Valve.
• Manual Radiator Valve.
• Dual-Fuel Radiator Valve.
• Traditional Radiator Valve.
• Modern Radiator Valve.
• Straight Radiator Valve.
• Angled Radiator Valve.
• Corner Radiator Valve.

Should radiator valve be open or closed?

Radiator valves, even though they have a handle, are not meant to be closed or half-open. Closing or opening the valve partially, will not control the heat coming from your radiator. Steam radiator valves must remain fully open at all times.

Do I need lockshield valve?

A lockshield valve helps to balance out that radiator and ensure the whole system is in sync, with all radiators heating at the same rate. It is therefore every bit as important a valve as without the system being balanced, there is often little point adjusting an individual temperature valve.

What does the lockshield valve do?

The Lockshield valve restricts hot water flow to radiators to help balance the entire system as a whole. Other radiator valves can be used to help adjust the temperature of a radiator to help heat or cool a room.

Which side of a radiator turns it off?

To turn a radiator off, locate the thermostatic valve on the left side and turn the valve clockwise until the dial reads 0. Next, find the second valve on the right side of the radiator and twist it clockwise until it won't turn anymore. Once both valves are closed, the radiator will be completely turned off.

Are both radiator valves the same?

Generally, there are two different style radiator valves (that are adjustable by the user) available. These are manual valves and Thermostatic Radiator Valves (also known as TRVs). Manual valves are quite simple devices that you can think of like a tap in your home.

How do you open a lockshield?

Once the system has cooled down, you will have to open the lockshield valve. To do this, simply turn in an anti-clockwise direction (to the left). You can do so by hand; but if your valves are a bit stiff, use your lockshield valve key, a spanner, or the wheelhead valve cap instead.

How do you adjust lockshield?

Flow valves or thermostatic valves (where fitted) are set to the fully open position and lockshield valves on all the radiators by turning them anti-clockwise. The plastic cap on the lockshield valve is removed and a small spanner or an adjustable spanner is used to adjust it.

What position should radiator valves be in?

Many modern homes will have TRVs – Thermostatic Radiator Valves – attached to most of the radiators on the opposite side from the lockshield valves. A TRV should always be fitted to the inlet on the radiator and the LSV to the outlet.

Why is my bathroom radiator always on?

Bathroom radiators are normally connected to the hot water circuit rather than the heating circuit from your boiler. This is so that it gets hot all year round for drying towels. It'll get hot whenever your boiler comes on to reheat the hot water cyclinder.

What position should a lockshield valve be?

The lockshield valve should be set to a degree that will allow the radiator or radiators to maintain their desired temperature.

What happens if a lockshield valve is closed?

On most radiators, this is the valve you can't turn by hand. By closing a fully-open lockshield valve by a few turns (with a pair of grips or screwdriver), you can slow down the rate at which water enters the radiator and reduce the speed with which it gets hot.
